Courier is a font, Draft is a quality. You can print any font the printer can print in any quality the printer can print, as long as the computer has that font installed. It sounds as if 3 of the computers don't have the correct Courier font installed, which would be strange, since Courier is installed in Windows.

Are you using the same printer, set up the same way, on all computers? (Or printing to the same networked printer in all cases?)
